Automatic parking device of bicycle

An automatic parking device of a bicycle comprises a front wheel groove used for containing a front wheel of the bicycle and transmitting the pressure of the front wheel of the bicycle downwards, a self-locking component hinged to the lower portion of the front wheel groove and capable of achieving self-locking at the lower position and releasing at the upper position alternately under the downward pressure of the front wheel groove, a lever mechanism hinged to the self-locking component, and a rear wheel clamping disc used for clamping a rear wheel of the bicycle, hinged to the other end of the lever mechanism, and capable of moving in a direction opposite to the vertical moving position of the self-locking component through the lever transmission function of the lever mechanism. When the front wheel of the bicycle presses the front wheel groove, the self-locking component is pressed to move downwards and is self-locked at the lower position, and meanwhile, the rear wheel clamping disc is ejected through the lever mechanism and clamps the rear wheel of the bicycle; when the front wheel of the bicycle presses the front wheel groove again, self-locking of the self-locking component is relieved, the self-locking component returns to the upper position, and meanwhile, the rear wheel clamping disc is pulled down through the lever mechanism and is disengaged from the rear wheel of the bicycle. The automatic parking device of the bicycle is simple in structure, convenient to operate, and capable of achieving automatic parking.

Lifting drive system by steel wire ropes in stereo garage

The invention discloses a lifting drive system by steel wire ropes in a stereo garage, wherein a motor drives a main drive shaft to rotate; lifting driven sprockets are arranged at two ends of the main drive shaft; front rings and back rings are arranged on the boundary beams of the four corners of a car carrying board; first pulleys and second pulleys are correspondingly and respectively arranged on the longitudinal beams, and third pulleys are arranged between the first pulleys and the second pulleys; lifting chains start at lifting eyes on the longitudinal beams, bypass the lifting driven sprockets and are connected with front lifting steel wire ropes which bypass the first pulleys and are connected with the front rings; one ends of the back lifting steel wire ropes are connected on the joints and the other ends thereof successively bypass the third pulleys and the second pulleys and are connected with the back rings. The system drives two lifting chains by one main drive shaft at the same time, and each lifting chain pulls the back lifting steel wire rope and the front lifting steel wire rope on one side of the car carrying board at the same time to realize the synchronous rising or falling of four lifting points of the car carrying board, wherein coiling blocks are not used during the driving. The system has the advantages of simple mechanism, low cost, and safer use.
